is emphasized that the engineering methodology enables artificial reservoir systems
to be created in the subsurface structure. A numerical simulation model which ex-
presses the complex distribution of natural fractures on the basis of fractal geometry
has been introduced and applied to field experiment with the objective of develop-
ing a quantitative basis for designing geothermal reservoirs in the complex natural
system. It is also proposed that this engineering methodology could also be applied
in order to tackle the common issue of the declining heat production in existing
reservoirs.
